Answer:
They are able to balance torques due to gravity.
Explanation:
When two friends of different masses will balance themselves on see saw then at equilibrium position the see saw will remain horizontal
This condition will be torque equilibrium position where the see saw will not rotate
Here we can say
here we know that force is due to weight of two friends
and their positions are different with respect to the lever about which see saw is rotating
since both friends are of different weight so they will balance themselves are different positions as per above equation
Answer:
The man has to aim 27.06 cm below the platform.
Explanation:
Given that,
Time = 235 millisecond
Speed = 13 m/s
We need to calculate the distance below the platform
Using equation of motion
Where, u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
Hence, The man has to aim 27.06 cm below the platform.
Its bituminous coal good luck :;;;;;;)
Answer:
They hit at the same time
Explanation:
The bullet that is fired horizontally, the horizontal component of the speed is the speed with which is its is fired and the vertical component of the speed comes in picture due to gravity only.
When the bullet is dropped from the same height, the horizontal component is zero but the vertical component arises from the gravity.
The vertical components of the velocity of both the bullets are same and thus, they fall at the same time.
<u>Answer: They hit at the same time</u>
Answer:
as its mass and velocity will less so its momentum will be less than that of baseball
